i have the reef octopus diablo 160X with the sicce pump and i have to clean it out every other day it pulls so much gunk also it is dead silent. i could not fit it in the fuge area of my pro flex because my stand was too short so i have it on the return side of the sump and maintain water level with a ATO. after having this skimmer for 2 months i kind of regret not getting a SWC tho. the venturi control on them is a nice feature
